Follow up history 1 month following treatment for these images: 43-year-old man has macular toxoplasmosis. He has responded nicely to Bactrim. He still has a spot in that eye, but it is no bigger. VISUAL ACUITY: OS: 20/60. IOP: OS: 18. The lens is clear. EXTENDED OPHTHALMOSCOPY: OS: Vertical C/D ratio is 0.2. The eye is quiet. The area of active toxoplasmosis is almost completely quieted. IMPRESSION: 1. HISTORY OF TWO EPISODES OF TOXOPLASMOSIS IN THE LEFT EYE. DISCUSSION: I explained to the patient that the left eye is quieting down nicely on the Bactrim. I asked him to continue the prescription twice a day until he runs out, and then to renew and take that once a day until he runs out, to return for a check in four to six weeks, sooner should he notice any problem.
